Aim: To assess whether optical coherence tomography (OCT) would be
sufficient to diagnose choroidal neovascular membranes (CNV) in the second
eye of patients who are already undergoing anti vascular endothelial growth
factor (VEGF) treatment of neovascular AMD in one eye
Methods: A retrospective chart analysis of the angiographic subtype of CNV in
the first eye of 30 patients undergoing treatment for neovascular AMD was
done. The angiographic features of the CNV in the second eye were compared
to that of the first eye. The OCT features of the eyes were also correlated with
the angiographic features.
Results: In 94% of cases, the angiographic subtype of membrane was similar
in both eyes with occult CNV being the most common sub-type. A few eyes had
classic membranes in one eye and occult in the other eye (6%).
Conclusion: There is a high chance of the second eye developing the same
angiographic sub-type of CNV as the first eye. Therefore, the second eye
may be commenced on treatment, based on the OCT morphology for activity,
without FFA/ICG.

Purpose-To describe the clinical and OCT features in a case series of acute
solar retinopathy. Methods-It is a descriptive case series of patients who
visited to our hospital with acute solar retinopathy from 2007 to 2010. 8 eyes
of 4 patients were analyzed Results-Among 4 patients only one patient has
bilateral central scotoma. The mean age of the patients is 23.25 years. The
visual acuity at the presentation is ranging from 6/24 to 6/9.Among eight
eyes four eyes regained 6/6 visual acuity where as the remaining four eyes
showed improvement in their visual acuity since the presentation. At the
presentation fundus examination revealed various foveolar changes including
exaggerated foveal refelex, yellow foveolar spot, red foveolar spot. All the
patients showed complete regression of clinical findings.OCT features of 2
patients showed hyper reflectivity of all retinal layers at the center of the fovea,
one patient showed hyper reflectivity in the outer retinal layers where as the
other patient showed cystic hypo reflectivity in the outer retinal layers at the
initial presentation.7 eyes showed complete regression of OCT features in
subsequent follow up examinations.
Conclusion: Acute solar retinopathy has characteristic clinical and OCT
findings and it carries good prognosis.

Objective: To study the clinical features and outcome of idiopathic CNVM in a
tertiary care centre. Design: Retrospective case series Materials and
Methods: Charts of all patients who presented with angiographically proven
idiopathic CNV from 2004 to 2010 were included
Results: 18 eyes of 18 patients with a mean age of 40 years (range 22-49
years)were analysed. The mean period of follow up was 12.9 months
(6-36months). Angiographically classic CNVwas seen in all the patients .
72% were subfoveal, 22.2% were juxtafoveal and 5% were peripapillary. The
treatment modalities included loading dose of Bevacizumab (Avastin) in 55.5%,
combination therapy with PDT and Bevacizumab in 16.67%, thermal laser in
5% , Bevacizumab on PRN basis in 11.1% and IVTA in 10%. 27.8% maintained
a stable vision, 55.5 % improved while 16.7% showed a drop in visual acuity.
Conclusion: Idiopathic CNVM carries good prognosis with timely intervention
usually with anti VEGF drugs

Congenital pits of optic nerve are rare anomalies occurring 1 in 11000 patients.
They appear as small hypo-pigmented grayish white, oval or round excavated
defects most often situated within the infero temporal region .This paper
highlights the various clinical presentations and treatment options available for
this infrequent yet challenging disorder.
Results: We had a series of 12 cases of optic disc pit with maculopathy. They
were followed up for a mean period of 27.5 months. 2 patients among them
underwent parsplana vitrectomy+endo laser+Intravitreal gas injection,
2patients underwent barrage laser+gas injection and 1 patient underwent
barrage laser alone. A 7 yrs old child was observed without any intervention.
Rest of the 6 patients were kept on follow up. One of the 2 patients who
underwent vitrectomy+gas injection+endolaser showed two lines improvement
in visual acuity and the other, one line improvement. Of the 2 patients treated
with gas injection and barrage laser, 1 patient showed one line and the other
two lines of improvement in visual acuity. There was two lines improvement
in visual acuity in the patient treated with barrage laser alone. Conclusion -
Optic disc pit maculopathy carries a reasonably good prognosis with timely
intervention

Purpose: To Examine Choroidal And Scleral Alteration At The Macular Area In
Tilted Disc Syndrome (TDS) With Posterior Staphyloma Using Optical
Coherence Tomography (OCT).
Methods: Choroid And Sclera Were Observed By Prototype High Penetration
OCT (HP-OCT). Choroidal And Scleral Thickness Were Measured At 1.5mm
Upper Area, Subfovea, And 1.5mm Lower Area On The Vertical Section Of
OCT.
Results: Fourteen Eyes (9 Patients) In TDS With Posterior Staphyloma At The
Fovea Were Included. Serous Retinal Detachment Was Confirmed In Seven
Eyes. Mean Choroidal Thickness Was 211±87?m At The Upper Area,
144±81?m At the Subfovea, And 156±49?m At The Lower Area. Each Choroidal
Thickness At the Subfovea And Lower Area Was Significantly Thinner Than
That At The Upper Area (P
