Know someone with keratoconus?

These are the 7 most important aspects of the condition that I share with every new patient that I diagnose with keratoconus:

[Colby Hart @DrColbyHart]

Honoured to win the 2023 Bowman Club Fellow’s Prize for my research on the role of artificial intelligence in diagnosing and predicting progression of microbial keratitis on anterior segment OCT.

AI will play a major role in our lives, personally and professionally!

[Colby Hart @DrColbyHart]

@rkuriakoseMD Nice - what were some take home messages?

We are about to publish a paper using deep learning to identify microbial keratitis on anterior segment OCT and to accurately identify if it is improving or worsening.

Will keep you posted!

[Colby Hart @DrColbyHart]

Fantastic to see @MrBeast sharing with the world the improvement in quality of life that can come from simple, cheap, effective eye surgeries! His best video yet!

[MrBeast @MrBeast]

We helped 1,000 people see, literally. Go watch the new video!

[Colby Hart @DrColbyHart]

@MrBeast Ah man, fantastic that you’re using your influence to improve peoples quality of life like this.

The satisfaction that can be received from improving peoples vision is the reason that being an ophthalmologist is the best job in the world!

Keep up the good work!

@kr156 Beautiful photo.

Is the mechanism of developing this understood?

My understanding is that there is an association with recurrent intracameral air or gas use.

Do you know if the patient required rebubbling post-operatively?

[Colby Hart @DrColbyHart]

@ValaAfshar The beauty of ophthalmology - simple interventions improving quality of life so rapidly.

The best use of science and tech is to improve quality of life https://t.co/RsNHnJ8Wlq

@drleylayavuz @Nemo_Patel_MD @efreneyemd @HoyekSandra Well done! What did you publish on?

[Colby Hart @DrColbyHart]

@simononaraigh Nice one mate.

Bonus points for:

- Most common bacteria associated with the condition?
- Medications that can cause the condition?
- Other system associations that should be asked about on systems review?

[Colby Hart @DrColbyHart]

Crystals in the cornea must be the most beautiful clinical sign in medicine.

Do you know the life threatening systemic associations with crystalline keratopathy?

[Colby Hart @DrColbyHart]

@HammadNasti @v_ophthalmology @RealWorldOphth @ophthalminute Yeah nice, can now. I remember seeing a similar thing with a patient who had GCA and this was happening to her retinal vessels 😬😬😬

[Colby Hart @DrColbyHart]

The central scar and iris adhesion made it impossible to complete the case without removing the cornea.

The way around this was:

- 8.25 mm trephine
- Careful dissection of the iris from the cornea
- Sacrifice of a small area of iris that was firmly adherent

@blakemama65 Glad it helped!

Know someone with keratoconus?

These are the 7 most important aspects of the condition that I share with every new patient that I diagnose with keratoconus:

[Colby Hart @DrColbyHart]

@kr156 We typically do angio guided cautery. Identify the feeding vessel, create a tract with a 30G needle at the slit lamp pre-op, use an electrolysis probe to cauterise. Sometimes with subconj avastin.

Do you think mitomycin has added benefit over this technique?

[Colby Hart @DrColbyHart]

@simononaraigh Nice one Simon. Have you seen a case before? Particularly difficult to suture into the thin ectatic tissue during penetrating keratoplasty.

[Colby Hart @DrColbyHart]

@HammadNasti Haha, no such thing as stupid guesses! This is a case of keratoglobus. The entire cornea is ectatic and thin rather than the inferior cornea as in keratoconus. We did a PK/phaco for this patient which was particularly difficult - suturing into such an ectatic cornea.
