report of adolescent boy.

1. Tadeusz Krwawicz Chair of Ophthalmology and Eye Hospital, Medical University
OBJECTIVE:Conversion disorder(CD) is a loss or distortion of neurological
function not fully explained by organic disease.Functional visual loss(FVL)
refers to subnormal vision or altered visual fields(VF) where no underlying
pathology of the visual system can be found.The preceding stressors or
conflicts are associated with the development of the disease.
Methods:We report a four year follow-up of 14 year old boy who presented with
significant visual loss and periodically recovery of vision. Performed full
ophthalmological examination : BCVA, fundoscopy, perimetry, color test,
patternVEP and clinical tests for FVL.He was referred to neurologic,
psychologic and psychiatric evaluation.
Results:Tests mentioned above confirmed diagnosis of FVL. During the first
year of follow-up the vision was reduced to CF.The family history revealed
alcoholism.The boy demonstrated symptoms characterized for CD:
psychogenic cough, psychogenic non epileptic seizures, tremor, fixed
dystonia, syncope and amnesis.He was referred to psychotherapy and was
removed from home to boarding school.Last 2 years of evaluation exhibits
some improvement-VA=1.0equally and normal VF with episodes of reduced
vision to CF.Neurological examination was normal.
Conclusion:A comprehensive examination should be performed to rule out
organic causes of visual loss.Isolated FVL has a good prognosis but with coexisting
CD is more likely to be persistent.

PURPOSE: To report a case of Retinoblastoma who presented with late clinical
sign of Rubeotic Glaucoma METHOD: Case report
Results: A 3 year old girl presented with left eye (LE) redness for 3 days
duration, following a fall at home. Examination of the LE revealed generalized
mild conjunctival injection and total hyphema. There was no squint noted.
B-scan revealed vitreous opacities possible vitreous haemmorrhage. She
was treated as LE trauma with total hyphema. Further history from her mother
revealed the child was having a white pupillary reflex since birth. Examination
under anaesthesia revealed intraocular pressure (IOP) of 46 mmHg, cornea
edema with diameter of 11.5 mm vertically and horizontally. Hyphema level
noted inferiorly with dilated pupil. The lens was covered with red blood cells
and was subluxated. No fundus view. An urgent CT scan of the orbit and brain
was performed showed left intraocular nodular calcification suggestive of
Retinoblastoma.
Conclusion: This case highlights the importance of recognizing atypical
features of Retinoblastoma, such as a subluxated lens and hyphema. Thus,
Retinoblastoma should be included in the differential diagnosis of hyphema
with subluxated or dislocated lens in young children.

Purpose : To report a case of combine acute CRAO with non-ischaemic CRVO
in a child Methods : Case report. A young boy, 10 years-old/ known case of
Nephrotic syndrome with multiple relapse and steroid responder presented
with sudden painless blurred vision of the right eye for 2 days. Results :
Visual acuity on his right eye was Hand movement with marked RAPD. The
anterior segment examination was unremarkable except both right and left
intraocular pressure were 29 mm Hg and 25 mmHg respectively. Fundus
examination on the RE showed evidence of palish retina with cherry red spot
and hyperremic optic disc.The veins were tortous with presence of scattered
retinal haemorrhage. However no emboli/ cotton wool spot seen. Prompt IOP
reduction and ocular massage was done to restore ocular perfusion. Clinically
he responded tremendously with reversibility of fundus finding after treatment
and his RE vision improve to 6/36
Conclusion : Prompt recognition, diagnosis and treatment are crucial in order
to minimize the functional ocular damage and restore ocular perfusion.

EFFICACY OF GREEN LASER PHOTOCOAGULATION FOR
AGGRESSIVE POSTERIOR RETINOPATHY OF PREMATURITY

Purpose. To estimate the efficacy of laser coagulation for patients with
aggressive posterior retinopathy of prematurity (AP-ROP). Methods. During
the period from May 2009 to January 2011, 18 premature infants (35 eyes)
with ÐÐ -ROP were observed. The mean birth weight was 1177,72+262,95 g.
Gestational age ranged from 24 to 32 weeks. To all infants laser coagulation of
avascular retina with near-confluent laser burns has been executed. Average
number of shots was 3100 per eye. The mean interval between birth and
carrying out of laser intervention was 7+2,94 weeks. The mean follow-up time
was 4,93+4,04 months. Results. The positive result of laser treatment has been
reached in 83% of cases - 29 eyes. On 26 eyes signs of regression of disease
were defined on the second week of observation. Repeat laser coagulation
was required for 3 eyes, after which regression was also observed. In 17%
the disease progressed to stage 5. Hyphema and anisocoria was observed
in 4 eyes after laser intervention. In the course of observation the condition is
normalizing. Conclusion. Тhe development of ÐÐ -ROP has increased lately.
It can form the basis for earlier screening and treatment. Our experience has
shown high efficiency of treatment of AP-ROP.

PURPOSE:This study evaluates optic coherence tomography(OCT) in
pediatric multiple sclerosis(MS) patients and retinal nerve fibre layer(RNFL).
Methods:12 children with MS diagnosed according to Mc Donald criteria were
included to the prospective and consecutive study.In Group 1, 4 MS patients(4
eyes) attacked optic neuritis(ON) from 1 eye;in Group 2, 8 MS patients(16
eyes, Group 2-a) not attacked ON and 4 other eyes(Group 2-b) of Group 1
patients not attacked ON and in Group 3, 12 healthy children(24 eyes) as
control group were examined.RNFL thickness was measured within all eyes
by OCT.The results were compared via analysis.
Results:Patients were followed approximately 28,82 (8-31) months.Average
period between diagnosis of MS and measurement of RSLT thickness
was 39,62 (13-58) months. RSLT thickness was found 84,51±21,58?m for
Group 1, 88,77±22,28?m for Group 2-a, 82,07±23,04?m for Grup 2-b and
98,04±21,35?m for Group 3.When Group 3 is compared with Group 1 and
Group 2-a,b, there is not statistically significant difference(p>0.05, p>0.05).
When Group 1 is compared with Group 2-b, there is not statistically significant
difference(p>0.882).
Conclusion:In pediatric MS patients, decrease in RNFL thickness is not
determined whether patient has ON attack or not.Further study should carried
out on this subject.
