Sepoy G. R. aged 26 years, first became aware of diminishing vision of his eyes in December 1967. At about the same time he realised that his night vision was also poor. These disabilities have since increased gradually. From September 1969 he complains of defective hearing as well.

When he was admitted in a hospital in January 1970 for swollen legs following prolonged marching, he first sought medical advice for the above disabilities. These were considered to be of psychogenic origin and he was transferred to our hospital for psychiatric treatment in February 1970. Since then he has been attending the ENT and Ophthalmic units of this hospital.

Present Ophthalmic Condition:

Both eyes are quiet and external examinations do not reveal any abnormality except that he tends to squeeze his eyes and see through narrowed slits of palpabral fissure. In both eyes, cornea are clear, anterior chambers clear, pupils react to light and accommodation and tension is within normal limits. In both eyes lenses show anterior and posterior lenticonus. [Figure - 1],[Figure - 2].

Fundus examination: In both eyes media are clear, discs normal. Vessels, specially the arterioles are attenuated in calibre. All over the fundi and more around the equatorial regions dull white deposits are seen. There are white dots, some are discrete and some confluent. Some of the white dots are also seen at the posterior pole. In both eyes, in the right more than the left pigmentary patches in the equatorial regions and beyond are seen. Few of these pigment patches are blotchy whereas few are seen as thin pigmented lines along the vessels in the periphery. There are no evidences of any haemorrhages or exudates.

Refraction: Retinoscopy gives a myopic reflex but the shadows are very irregular due to lenticular astigmatism. His unaided vision in each eye 3/60 N12 improves to 6/24 N10 with -3.5 D sph. with -3.5 D cyl. 90°

Colour perception: Normal by Ishihara

Fields: Generalised contraction in both eyes.

Night vision: Poor

Other associated disabilities:

(a) Deafness in both ears

(b) Inadequate personality with a foolish look and mental retardation.

Personal History: He could study upto the 8th standard.

He smokes one packet of bidi daily and drinks occasionally.

He is married and has one daughter.

Family history: His father has four sons and one daughter by his first wife and two sons and five daughters by his second wife. None of his brothers or sisters are suffering from any visual disabilities that he knows of. He cannot say this about his mother or maternal uncles and their off springs.

Laboratory investigations: All tests including, C.S.F., and serology for W. R. & K. T. are within nomal limits.

Tapeto retinal degenerations are frequently associated with other ocular and systemic degenerations.

Among the lenticular changes associated with tapeto retinal dystrophies, posterior cortical cataract of the complicated type has been recorded which appears earlier in a dominant than in a recessive trans­mission. A malformed lens has also been recorded so also a congenital cataract. [3]

Simultaneous existence of both anterior and posterior lenticonus in both eyes is an extreme rarity and its association with tepeto-retinal dystro­phies has not been recorded earlier.

Besides this the case also has associated deafness and mental back­wardness which has been recorded by various authors earlier . [4]
