Objective: To present a valsalva retinopathy case during labor in a 29 years old
female.
Methods: Case Report
Results: A 29-year-old woman during labor presented with a history of
decreased vision in her right eye. Examination of the affected eye showed
best corrected visual acuity of hand movement, and fundus examination
revealed an extensive pre-retinal hemorrhage covering almost all the macula.
We performed a successfull hialoidectomy with ND:YAG laser and the vitreous
hemorrhage created was selfsolved within one week. final best corrected
visual acuity of the affectd eye was 20/25 and in the funfus examinations a
epiretinal membrane was found.
Conclusion: There are a few cases of valsalva retinopathy reported in the
literature, none as extensive as this case, in all cases, the Nd:YAG laser
treatment were susccessfull. As our patient, all of the patients developed
epiretinal membrane

Purpose : To assess morphological changes of the retina in occult macular
dystrophy (OMD) by using spectral domain optical coherence tomography
(SD-OCT).
Methods: Retrospective observational study. We evaluated the findings of SD-
OCT in five patients who had a normal ocular examination and low voltage
in multifocal electroretinograms. Central foveal thickness (CFT) and outer
nuclear thickness (ONT) in OMD was measured and compared to that in
normal volunteers.
Results: The mean CFT and ONT in the patients were 143.2 ?m ± 20.2 (SD)
and 80.3?m ± 15.73 (SD) and significantly thinner than those in 35 normal
volunteers. The intermediate line between layers of the retinal pigment
epithelium disappeared in all eyes of the patients.
Conclusion:?The photoreceptor cells including the outer segment are affected
in the eyes with OMD. OCT findings are valuable to improve the accuracy of
diagnosis and elucidate the pathogenesis of OMD.

eye drops to the stability of tear film and dry eye.

Purpose: To evaluate and analyse changes of tear film break-up time (BUT)
after intravitreal injections of anti-VEGF (Bevacizumab) and prophylactic use
of broad spectrum antibiotic eye drops (Levofloxacinum).
Methods: In the study group we included 30 eyes treated with anti-VEGF and
in control group we included the fellow eyes. We examine BUT and compare
results of both groups.
Results: In the study we included 30 patients (13 - male, 17 - female) from age
36 to 92 (average - 73 years). The number of intravitreal injections was from
1 to 22 (median - 3). The mean tear film break-up time in the study group was
8,23seconds (SD - 1,74), but in control group the mean BUT was 8,00 seconds
(SD - 1,86).
Conclusion: Our results show that use of intravitreal anti-VEGF agents and
prophylactic use of broad spectrum antibiotics do not have essential impact on
the tear film stability and dry eye.

Observational study on the role of presenting vision on visual
outcome in Wet Age-related Macular Degeneration (AMD) in a onestop
district general hospital in UK

Objectives: To determine importance of presenting vision in patients with wet
AMD and to assess it›s effect on visual prognosis following treatment.
Methods: Retrospective study of 167 patients (201 eyes) treated for wet-AMD
between February 2009 to August 2010 in a secondary care retinal practice. All
patients included in the study received at least 3 loading doses of Ranibizumab
at 4 weeks interval after confirming diagnosis by clinical examination, Fundus
Fluorescein Angiography & Optical Coherence Tomography. A trained nurse
specialist recorded Best Corrected Visual Acuity (BCVA) using the Early
Treatment of Diabetic Retinopathy (ETDRS) vision chart at first visit and then
at subsequent visits.
Results: 187 eyes met the inclusion criteria. In patients with presenting vision
between 75-45 letters (0.3 - 0.8 Log MAR) 61% showed an improvement in
vision and 17% worsened. Among those with < 45 letters (0.8 Log MAR), only
28% improved and 51% deteriorated even after treatment irrespective of the
type of lesion.
Conclusions: Increase in BCVA after Ranibizumab treatment is well established.
This study highlights that visual prognosis is much better in patients with
presenting vision >45 letters. The beneficial effects of ranibizumab are more
significant when treatment is started early and prompt referral pathways are
crucial to avoid delay in assessment and treatment of wet AMD.

maculopathy associated with Optic disc pit

Purpose : To evaluate the efficacy of peripapillary laser treatment and gas
tamponade as a treatment modality for macular detachment associated with
optic disc pit Design : Noncomparative, interventional case series involving 8
consecutive patients presenting with unilateral macular detachment associated
with an Optic disc pit Intervention : LASER photocoagulation to the area of pit
and intravitreal injection of 0.3 cc C3F8 gas with face down positioning for 10
days. OCT used to monitor the anatomic changes, with a follow-up of 3 months
to 12 months (mean 6.5 months). Results : Complete retinal reattachement
was observed 6 out of 8 eyes. The mean pretreatment BCVA was 0.88 logMAR
units and mean posttreatment BCVA was 0.40 logMAR units. More than 3 lines
of BCVA gain was observed in 4 out of 8 eyes. Secondary Glaucoma was
observed in 1 eye and none of the eyes required retreatment.
Conclusion : Results suggest that peripapillary laser and gas tamponade is
successful in treatment of macular detachment, improving central vision in
patients with Optic Disc Pit.
