Inspite of adequate publicity about the adverse effects on the eye from visualising solar eclipse through the various mass media, many enthusiasts did visualise the solar eclipse on Feb. 16, 1980. Immediately after exposure to the eclipsing sun, the persons involved started attending our institution with or without symptoms. Five ophthalmologists were invol­ved in a joint study of 379 cases.


  Material and methods Top


Out of 379 patients, 33 were admitted. The study involved following parameters : age, sex, refractive status, methods of viewing, grades of damage, effect on vision, damage to macula, cornea, conjunctiva etc. and recovery after treatment.

Positive findings were documented in colour transparencies. The Results were recorded.

Following was the treatment given

Local

(i) Hycin fortified eye oint.-t.i.d.

(ii) Retrobulbar Injection­

Arlidine (0.5 cc) Decadron (0.5 cc)

- daily for exudative cases (total 7) - alternate days for Oedema cases

(total 4)

Systemic

(i) Tab. Decadron 2 t. i. d. X 5 days and then slowly tapered

(ii) Tab. Camplamina I t. i. d. X 5 days (iii) Tab. Multivitamin/B Complex I bid.


  Observations Top


All were deliberate viewers. The majority of these patients (305) were males. The age group maximally involved was 21-30 yrs. [Table - 1]

The involvement was bilateral in the vast majority (366 out of 379). The viewing was with naked eye in 178, through film negative in 159 and miscellaneous in 42 cases. The approxi­mate duration of viewing was 5 seconds to 15 minutes.

Out of 3799 cases, macula was obviously involved in 140. The refractive states were emmetropia-92, myopia-40,hypermetropia-7 and aphakia-1. The macular oedema was mild in 93, moderate in 30 and marked in 17. Exudates were noticed on the fovea in 18 cases and in the parafoveal area in 12. Inspite of energetic treatment the oedema persisted in 7 cases up to 6 months. Punctate haemorrhage was seen in 2 cases. Indefinite pigment change was seen in 15 cases. The result : Pigmentary degeneration of the macula in 7 cases with visual acuity (V.A.) less than 6/60; lamellar holes in 3 cases with V.A. less than 6/24 and holes round the macula in 2 cases with V. A. less than 6)36.


  Discussion Top


Viewing of Solar Eclipse directly gives rise to solar macular retinitis in majority of cases.

More the duration of visualisation, more the damage. Shorter duration of visualisation mostly results in macular edema. But duration more than 2 minutes resulted in macular burn.[5]
