1.Retinitis pigmentosa 2. triad of arterial attenuation , waxy pallor of Optic disc and black bony spicules due to RPE changes. Also pt complaints if night blindness with progressive loss of peripheral vision. 3. investigation is mainly dilated fundus examination , ERG , VFA, EOG, VEP , dark adaptation test 4. systemic syndromes associated with RP are Bardet- Moon- biedl syn, Usher syn , abetalipoproteinemia , Kearns- Sayre syn 5. there is no treatment as yet..retinal implant can be done in selected cases .this disease is herediatry with rod dysfunction and vision loss is progressive. Low vision aids can be prescribed along with genetic counselling.

1) Retinitis Pigmentosa 2) Arterial attenuation, waxy palor disc Nd pigmentry disturbances in form of bony spicules.. 3 ) Investigations a)perimetry -involve mid periphery in early stage known as ring scotoma..later tubular vision b ) erg - decreased amplitude c) eog 4)m.c systemic association - usher syndrome (r.p + deafness )..oders moon biedl synd , laurance synd etc. 5 ) treatment - no effective treatment Vit A for rods Vit E as anti oxidant

Retinitis pigmentosa.

retinitis pigmentosa. no treatment..

..RP.... in private practice,. we are little less elaborative...we get used to jumping to diagnosis..

True maam. but we being in medical colleges try and discuss everything at length so that our post graduates learn some points from every case.
