7

Inflammation of the eyelid

Blepharitis

8

- Lipogranuloma in the eyelid
- Obstruction of sebaceous ducts leading to granulomatous inflammation

Chalazion

9

Most common malignancy in the eyelid

Basal cell carcinoma

10

May mimic chalazion clinically
May metastasize

Sebaceous carcinoma

11

Clamydia trachomatis (trachoma) has

Significant conjunctival scarring

12

Has Delle
- saucer-like corneal depression due to focal dehydration

Pinguecula

vs Pterygium
- NO delle
- has corneal invasion
- Astigmatism

BOTH
- actinic (sun-induced) damage
- submucosal fibrovascular CT

13

Saucer-like corneal depression due to focal dehydration seen in Pinguecula

Delle

14

- Actinic damage
- has vidual problems (astigmatism)
- has corneal invasion

Pterygium

15

Most common site of conjunctival lesions

Limbus

16

Brown color of uvea appears blue

Optical Tyndall effect

17

Blue sclerae seen in:

- osteogenesis imperfecta
- scleral ectasia (in increase IOP)
- congenital melanosis oculi
- nevus of Ota

HSV

22

Keratitis and ulcers
Notable organisms

- HSV
- VZV
- Acanthameoba (swimming pool)

23

It accelerated dissolution of corneal stroma

Collagenase activation

24

Collection of pus in anterior chamber

Hypopyon

25

Brown lens is due to

Urochrome deposition

26

Cataract causes

- systemic diseases (galactosemia, DM, Wilson disease, atopic dermatitis)
- corticosteroids
- radiation
- trauma
- electrical burns
- age-related (nuclear sclerosis)

27

Disease characterized by distinctive changes in the visual field and optic nerve cup

Glaucoma

28

Associated with increased IOP

Glaucoma

29

- NO trabecular meshwork access
- peripher zone of the iris ADHERES to the trabecular meshwork
- Acute

Angle - closure glaucoma

30

- THERE IS trabecular meshwork access
- INCREASE resistance to aqueous outflow in open angle of the anterior segment
- chronic

Open - Angle glaucoma
