id:: 33644eee-3af2-4d56-8089-32a582fb4f8d
- | Traits | Immature Cataract | Mature Cataract | Hypermature Cataract |
| ------------- | ----------------- | --------------- | ----------------------- |
| Visual Acuity | upto 6/12, 6/18 | 6/36, 6/60 | Hand movement to PL, PR |
| Colour | Grayish white | Pearly white | Milky White |
| Iris shadow | present | absent | absent |
| Fundal glow | present | absent | absent |
- ## Diagnosis
background-color:: blue
- ### Clinical Diagnosis
- #### Classical Presentation #classical-presentation
- Old Age, above 60
- Gradual Dimness of Vision for past few years
- Visual Acuity reduced to hand movement
- Color of lens milky white
- Iris shadow absent
- Follow ((33644eee-3af2-4d56-8089-32a582fb4f8d))
- #### Probable Diagnosis
- ### Examination
- _General Examination of the patient should be done to determine the presence of serious systemic disease_
- Visual Acuity
- Pupillary light reflex [Direct, consensual]
- Color of lens [Torch examination]
_grading of nucleus hardness_ by [[LOCS]]
- ((674f65c1-fc03-4bf1-ab74-bbb1463be2f2))
- The grading of nucleus hardness is useful to the cataract surgeon in planning surgery by phacoemulsification
- [[Intraocular Pressure]] [Digitally]
- Retinal and Optic Nerve Function
_If the fundus cannot be seen, 5 tests are of value_
- Detection of the projection of light
- Macular function
- Entopic view of the retina
- Ultrasonic investigation
- foveal electroretinogram
- Sac resucsitation test
- Additionally,
- Ocular Motility
- Fundoscopy
- ### Investigation
- #### Systemic Investigation
- ECG
- Blood Sugar profile, HbA1c
- #### Ocular Investigation
- [[Biometry]]
- [[Keratometry]]
- [[B scan]]
