1. National Eye Hospital
A case report of a 26 years old woman with bilateral multiple prepapillary
vascular loops and vitreous haemorrhage in the left eye. Colour fundus
photograph and fluoresceine angiography of the condition are presented.
These loops are normal retinal blood vessels that have grown into the
Bergmeister papillae before returning to the optic disc. The loops are 0.5mm
to 5mm in length. They are congenital in origin. Spontaneous resorption of
vitreous haemorrhage is the rule and the prognosis is excellent.

PURPOSE: Togive an overview of blue peak fundus autofluorescence (FAF)
imaging and its applications in evaluation of retinal diseases MATERIALS AND
Methods:FAF imaging was performed in normal eyes in all age groups (30-
70yrs) and also in various retinal diseases.
Results:Blue peak autofluorescence pattern is a combination of blue laser and
confocal scanning, which helps in mapping of lipofucsin, a naturally occurring
metabolic indicator found in retinal pigment epithelial(RPE) cells. As various
hereditary and acquired retinal disorders manifest with altered metabolic
activity of the RPE-photoreceptor complex, FAF helps in identifying the
changes in FAF pattern in these disorders.
Conclusion: Blue peak autofluorescence serves as a newer non-invasive
diagnostic modality which helps to diagnose and provide an insight into the
visual prognosis of macular disorders.

Case report : A 30 year old male patient of Chronic Myeloid Leukemia, on
Imatinib Mesylate since 5 months presented to us with bilateral diminution of
vision of 2 weeks duration.His best corrected visual acuity was [RE] 6/18 and
[LE] 6/24.On examination, anterior segment was normal in [BE] and fundus
showed bilateral serous elevation of macula with subretinal precipitates
and retinal folds.FFA showed small multiple hyperfluorescent spots in the
perifoveal area increasing in size and intensity with subretinal pooling of dye
in late phases, simulating central serous chorioretinopathy.OCT confirmed
the findings. Discussion : Central serous chorioretinopathy like picture in this
patient may be due to fluid retention,an adverse effect of Imatinib Mesylate.
There are very few cases of subretinal fluid retention reported sofar.Causes
are speculative,may be due to downregulation of kinases like Platelet Derived
Growth Factor Receptor, which are expressed in retina.

Objective: To report a case of congenital nystagmus whose cone dystrophy
was revealed at age 4 years by electroretinogram (ERG) and spectral domain
optical coherence tomography (OCT). Case report: A 4-months-old male
baby referred to us with congenital nystagmus. The baby was born normal
delivery and had no familiar history. The nystagmus was involunlary, repetitive,
to-and-fro oscillation. His refractive state was 3.5~4.0D hyperopia in both
eyes. Anterior ocular segment and ocular fundus were normal in both eyes by
ophthalmologic examination. He was treated with glasses under diagnosis of
ametropic amblyopia at age 2 and half years. His visual acuity was 0.09 in both
eyes at age 4 and half years. ERG revealed that rod and maximal responses
was normal or slightly decreased, but the cone and 30Hz flicker responses
were flat. At age 5 years, OCT revealed that reflection of photoreceptor inner
and outer segment junction was unclear in the macular area. At age 6 years,
the visual acuity remained 0.07 in right, 0.09 in left eye. Cone and flicker
responses were non recordable in both eyes.
Conclusion: Cone dystrophy was diagnosed by ERG and OCT in a baby with
congenital nystagmus whose fundus appeared normal.

Introduction: Central serous retinopathy although not typical has been reported
to occur during pregnancy and is known to be self limiting. Case report: A 27
year old female presented with blurred vision and distortion of images in her
left eye since one week in the seventh month of her second pregnancy. On
examination the visual acuity of right eye was 6/6 and in the involved left eye
it was 6/12. Amsler grid of right eye was normal, left eye showed distortion
of the central area. Dilated fundus examination revealed a normal right eye
and left eye showed a round, serous elevation of the retina measuring two
disc diameters in size involving foveal center with subretinal exudates. OCT
showed a serous retinal detachment at macula. A week later patient reported
an improvement in vision but distortion persisted. A month later visual acuity
improved to 6/9. Fundus examination and OCT showed resolving serous
detachment with persisting subretinal exudates.
Conclusion: CSR in pregnancy is rare, 61% of which occurs in the third
trimester. The condition resolves spontaneously in the first few months postpartum.
This case report reaffirms the self limiting nature of the disease even
in pregnancy.

Introduction: We report a case of toxic optic neuropathy caused by a window
washer fluid containing methanol. Case: A 47 - year-old male had alcoholism.
He drank alcohol for a week and took a window washer fluid on the last two
days. He became ill due to acidosis and his visual acuity fell to light sense in
both eyes. Fundus showed swelling of the optic disc but the macula appeared
normal. MRI revealed a high signal in bilateral basal ganglia in his brain, which
suggested methanol toxicity. High concentration of methanol was detected in
his urine. Emergent dialysis was performed. At day 8, best corrected visual
acuity (BCVA) improved to 1.2 in both eyes. At day 40, spectral domain optical
coherence tomography showed thinning of inner retina and retinal nerve fiber
layer defect in the macula. Optic disc swelling disappeared and optic disc
cupping was enlarged. At 7 months, right BCVA was 0.2 and left was 0.02.
Both optic discs were atrophic. Visual field was constricted in the right eye and
a central scotoma remained in the left eye.
Conclusion: Methanol optic neuropathy involved retinal nerve fiber layer defect
and thinning of inner retina.
