keratoconjunctivitis should be suspected in patients who have ocular
surface symptoms and report a metallic taste in their mouth and who
handle zoanthids, as occurred in case
1. After excluding the infectious
causes, toxic keratoconjunctivitis
might be treated with aggressive use
of topical corticosteroids as well as
topical cyclosporine and lubricants.

a rare anomaly characterized by multiple grouped, white, variably sized,
albinotic spots. They generally involve the peripheral retina, similar
to that of bear track grouped pigmentation.1 Usually the macula is
spared, and the spots may occur in
one or both eyes. The lesions seem
to be stable, and visual acuity, visual fields, color examination, dark
adaptation, and electrophysiologic
findings are normal. There is only
1 report of a decrease in visual acuity in this entity.2(pp614-615) Fluorescein angiography revealed a variable pattern related to the choroidal
fluorescence seen through these lesions that was considered sporadic
and rare in frequency. In this article, we describe 4 cases that occurred in a Brazilian family of Italian descent. This is the first reported
instance of familial CGARPES.
Report of Cases. Case 1. A 19year-old woman was referred for
evaluation after her general ophthalmologist noted areas of retinal abnormality on ophthalmoscopy after a routine refraction. She had
occasional headaches but no specific ocular symptoms, and she was
in excellent general health. Visual

acuity was 20/20 in both eyes with
−0.50 cylinder correction in the left
eye. Slitlamp examination of the anterior segments and vitreous cavity
was unremarkable. Intraocular pressures were normal. Funduscopy of
both eyes revealed multiple white
and sometimes yellow flecks of variable size and configuration affecting all parts of the retina (periphery, equator, posterior pole, and
fovea) (Figure 1). The size of the
flecks was highly variable, from the
diameter of one vessel to 4 times
the diameter of the optic nerve but
the flecks had a consistent color pattern: in the smaller lesions, the color
was more homogeneous, and in the
larger lesions, it was concentrated at
the edge of the flecks (Figure 1).
Fluorescein angiography showed a
normal choroidal and retinal vascular perfusion. The arterial phase revealed a transmitted hyperfluorescent lesion (a window defect of the
retinal pigment epithelium) that corresponded to the lesions seen during the ophthalmic examination. No
intraretinal fluid was seen during
the late phase of the angiogram
(Figure 1).

electrooculogram, electroretinogram, and visual field were normal.
Follow-up 1 and 5 years later
showed the same ocular fundus findings without progression of the
flecks, and the headaches had disappeared. There was no history of
consanguineous marriage. When
other members of the family were
examined, this unusual fundus was
observed in her 2 sisters and her
mother (Figure 2).
Case 2. A 39-year-old woman,
the mother of the patient described
in case 1, described no ocular or systemic symptoms. Her visual acuity
was 20/20 in both eyes, with normal visual fields and no clinical night
blindness. Results of anterior biomicroscopy examination, color testing (Farnsworth dichotomous
D-15), electroretinogram, and electrooculogram were normal. Color
fundus photographs showed deep lesions of the fundus, similar to those
seen in case 1. The same color pattern was seen: more homogenous
color in the smaller lesions, and color
concentrated at the edges of the
larger lesions (Figure 3). The ocular coherence tomographic findings of a small fleck showed no defect in the inner or outer retina.
Case 3. This 16-year-old girl is the
sister of the patient described in case
1. Her corrected visual acuities were
20/20 in both eyes. Her visual fields
were normal, and she had no night
blindness. Retinal flecks were present in the posterior pole and all fundus quadrants up to the periphery.
However, the lesions were smaller
than those seen in either case 1 or
case 2 (Figure 4).
Case 4. A 12-year-old girl, the
youngest sister of cases 1 and 3, was

also healthy, with 20/20 visual acuity and normal visual field without
clinical night blindness. Both eyes
were affected with fleck lesions,
comparable in shape and distribution with the flecks seen in the eyes
of her 2 sisters and mother. As in her
16-year-old sister (case 3), the fleck
lesions were smaller but were distributed from the macula up to the
periphery in all quadrants.
Comment. The retinal condition
in the patients described in our article is compatible and consistent
with a diagnosis of congenital
grouped retinal pigment epithelial
spots. The 4 cases were characterized by bilateral, multiple, deeply
situated, white-yellow fleck lesions
with a panretinal distribution (fovea, posterior pole, peripapillary,
equator, and periphery). However,
the lesions in original reports of
CGARPES tended to be white, spare
the macula, and uniocular.1,2 On the
other hand, our and more recent articles3,4 found those spots to be bilateral, affecting the macula and present with some yellow lesions,
particularly in the posterior pole
area. We hypothesize that yellow
macular lesions could be explained
by the increased amount of xanthophyll in these areas compared
with the periphery, where the spots
are white. Like in all reports of
CGARPES, the lesions vary in size

and configuration; however, we believe there is a color pattern: larger
lesions tend to have heterogeneous
coloration between the edge and the
central part; smaller lesions tend to
be more homogeneous.
According to Gass,2 the spots may
represent focal thickening of the retinal pigment epithelium that is filled
with a white material that may be diffusely distributed or more concentrated in the periphery of the lesion. Histologic findings have not
been reported so far to clarify the
true composition of this material.
Fluorescein angiography showed
hyperfluorescent spots with the initial phase of the angiogram (window defect) correlating exactly with
the lesions observed in the ocular
fundus. This finding is well documented in previous articles.1,2,4 The
differential diagnosis of CGAREPS
includes fundus flavimaculatus, fundus albipunctatus, and familial drusen. Gass2 recognized that CGAREPS
is identical to the entity reported by
Kandori and colleagues, 5 sometimes referred to as the flecked retina
of Kandori.
In contrast to previous studies that
found this entity to be sporadic, we
found an obvious familial component in our cases. The hereditary pattern in the presently described family is most likely an autosomal
dominant form of the disease since
only the mother and 3 daughters pre-

sent with the unusual fundus. However, because only 2 generations were
analyzed, the pattern is also consistent with autosomal recessive, Xlinked dominant, digenic, or mitochondrial inheritance. Because this is
the first report of CGARPES in more
than a single family member, we believe the appropriate name for this
unique presentation is familial congenital grouped albinotic retinal pigment epithelial spots.

Immune Choroiditis
Following Contralateral
Acute Retinal Necrosis
Acute retinal necrosis (ARN) syndrome is characterized by acute
panuveitis and retinal arteritis that
progresses to a diffuse necrotizing
retinitis with late-onset rhegmatogenous retinal detachment.
The contralateral eye is involved in 10% of patients despite systemic antiviral treatment. 1 It is
thought to occur because of retrograde axonal transport between
the suprachiasmatic nucleus of
the hypothalamus and the contralateral retina in an animal model.2
Bilateral ARN is characterized by
bilateral foci of retinal necrosis
associated with arteritis and panuveitis. However, a noninfective
choroiditis in the contralateral eye

Report of Cases. Case 1. A 54-yearold white woman was referred for
treatment with a diagnosis of presumed ARN in her right eye. There
was no other relevant medical history. Her best-corrected visual acuity (BCVA) was 20/200 OD, 20/20
OS. On examination, the right eye
had panuveitis with retinal necrosis and associated arteritis. There was
also a relative afferent pupillary defect in the right eye. The left eye was
unaffected. Vitreous biopsy confirmed herpes simplex virus–
associated ARN by polymerase chain
reaction. She began taking 10 mg/kg
of intravenous acyclovir 3 times per
day for 7 days followed by 500 mg
of oral valacyclovir 3 times per day
for 3 months. Four months later, the
right eye became phthisical owing to
persistent inflammation despite topical corticosteroids. Ten months later,
the right eye was no longer inflamed but she had increasingly
blurred vision and mild discomfort
in her left eye. Her BCVA was 20/40
OS. Anterior segment examination
revealed a white eye with mild inflammation and a cataract. There was
minimal vitritis, and fundoscopy revealed disc swelling with multiple
deep pale lesions throughout the
fundus (Figure 1A). Fluorescein
angiography showed early hyperfluorescensce of the choroidal lesions with late staining accompanied by perivascular and optic disc
leakage of dye (Figure 1B). A vitreous biopsy was performed and was
negative for herpes simplex virus,
Varicella zoster virus, cytomegalovirus, and Epstein-Barr virus. The
sensitivity for detection of virus by
polymerase chain reaction in ARN
at our institution was 87.5%.3 With
suspicion of atypical presentation of
bilateral ARN, she started taking 500
mg of oral valacyclovir 3 times per
day and 40 mg of prednisolone once
per day. Her BCVA improved to
20/20 OS. During the next 12
months, her visual acuity diminished to 20/40, partly owing to a
cataract that was removed with a
perioperative intravitreal triamcino-
